75% of the world's energy is consumed in cities. 40% of the world's energy is consumed in buildings. The most interesting potential for CO2-reduction in cities from an economical point of view lays in the modernization of the builing infrastructure. Making existing and new buildings to Green Buildings is one of the most effectice levers to meet the challenges of CO2 reduction in cities. Siemens as endorser of the Green Building program of the European Union has already implemented several projects for the program. The objective of the presentation is to give a short overview of the frame conditions, the existing labels and – most important – show success stories.
